The video you see above comes from an AAU basketball game between 3rd graders in Ardsley, New York this weekend and shows one team’s coach attacking a parent of an opposing player immediately after the game. According to the Instagram uploader, the coach was arrested following the assault.

I’m not sure what happened between the coach and parent to provoke this, but it’s always tough to see grown adults who are trusted with instilling leadership and strong character in young children set such a horrible example by doing something like this.
